Definitions

  • the invention relates to a basic frame on the carrying chassis of a truck for receiving units changeable in their orientation and extendable in a plurality of directions, especially for military applications, which has struts extendable in the direction of width and has supports arranged at the end thereof that are vertically lowerable, whereby the extendable struts, which are guided in a transverse hollow beam that is part of the basic frame, are telescopically movable in the longitudinal direction into a desired extended position by a signal transmitted by a control device.
  • electromechanical switches that are arranged on the hollow beam, such switches having switch feelers extending through the wall of the hollow beams and being adapted to act upon the switches in response to switch actuating recesses in the telescopic struts in a manner independent of inaccuracies in manufacture (play) between the hollow beam and the telescoping struts.
  • the switch is provided with a floating switch feeler and a floating leveling feeler which are movable independent from each other.
  • the switch actuating recess or groove is in a position underneath the moving switch feeler, the switch feeler drops into the recess or groove, while the leveling feeler continues to ride over the outer, grooveless surface of the strut. Therefore the switch feeler will always move the distance a (see FIG. 4) independently of the inaccuracies of manufacture (play) between the struts and the hollow beam.
  • the housing of the switch is fixedly connected to the leveling feeler and the switch element of the switch is fixedly connected to the switch feeler.
  • the leveling feeler which is in the form of a tube, is arranged in a bearing housing that is fixedly connected to the hollow beam so that the leveling feeler may slide in its longitudinal direction inside the bearing housing.
  • a compression spring is arranged between a sliding shoe that is fixed to the lower end of the leveling feeler and the lower edge of the bearing housing.
  • a compression spring is arranged between an abutment at the switch feeler, which at its free end carries a follower roller, and a bearing bushing, which is provided inside the bore of the tubular leveling feeler.
  • the bearing bushing is fixedly connected to the leveling feeler and surrounds the switch feeler so that the bearing bushing and the switch feeler are slidable relative to one another. This ensures that the entire switch is arranged floatingly in its direction of actuation in relation to the extendable telescopic struts and the stationary hollow beam of the strut system so that assembly and manufacturing inaccuracies (play) between the elements of the strut system that are sliding relative to one another do not effect the actuating distance (travel) of the switch.
  • the switch and its switching element which at its end bears a follower roller, are arranged perpendicularly in relation to the switch feeler.
  • the switch feeler At the upper end of the switch feeler there is a slanted surface, which the follower roller of the switch element contacts.
  • the leveling feeler has a slot-like opening, approximately as long as the plane of the slanted surface of the switch feeler, to allow the follower roller to penetrate.
  • the upper end of the leveling feeler is connected to the switch by means of a angle piece made of sheet metal. In this manner an especially flat configuration of the detecting or switching means is achieved.
  • FIG. 1 is a perspective view of a basic frame for mounting on the carrying chassis of the truck;
  • FIG. 2 shows the extending telescopic unit, associated with the basic frame, including the switching means
  • FIG. 3 shows a switching means in section
  • FIG. 4 shows a further possible embodiment of the switching means in accordance with FIG. 3 in a cross-sectional view
  • FIG. 5 shows part of the structure of FIG. 4 in a cross-sectional view along the center line of the switch feeler.
  • FIG. 1 shows a basic frame 16 mountable on the carrying chassis of a truck.
  • the basic frame 16 which is not described in detail has telescopic structures comprising hollow beams 3 in which struts 1 and 2 are arranged for a telescopic movement and, when the telescopic struts 1, 2 are extended, supports 17 permanently mounted on the ends of the struts 1,7 may be lowered to the ground so that military equipment such as a rocket launcher or signaling equipment mounted on the basic frame may project to the side without the truck being likely to topple over.
  • telescopic structures comprising hollow beams 3 in which struts 1 and 2 are arranged for a telescopic movement and, when the telescopic struts 1, 2 are extended, supports 17 permanently mounted on the ends of the struts 1,7 may be lowered to the ground so that military equipment such as a rocket launcher or signaling equipment mounted on the basic frame may project to the side without the truck being likely to topple over.
  • FIG. 2 shows the telescopic unit with outer hollow beam 3 in which the struts 1 and 2 with the terminally mounted vertical supports 17 are arranged.
  • the supports 17, when necessary, may be lowered to the ground.
  • On both sides of the hollow beam 3 a respective detecting or switching means 4 is arranged.
  • the same consists of a switch 14 and a leveling feeler 7, which are connected together by an angle member 24 made of sheet metal.
  • recesses or switch actuating grooves 5 are arranged in the outer part of the struts 1, 2 recesses or switch actuating grooves 5 are arranged.
  • FIG. 3 shows a switching means 4 in a cross-sectional view.
  • the housing of the switch 14 is fixedly connected to a leveling feeler 7.
  • the leveling feeler 7 is arranged to slide in a bearing housing 15 which is permanently connected to the stationary hollow beam 3.
  • a sliding shoe 10 is secured, which bears against the outer wall of the respective moving strut 1 or 2.
  • a compression spring 8 which is mounted with a compression bias or load.
  • a switch feeler 6 is fixedly connected to the switch element of the switch 14. At its lower end the switch feeler 6 has a follower roller 11, which bears against the outer wall of the struts 1 and 2.
  • the switch feeler 6 extends through the interior of the tubular leveling feeler 7.
  • the switch feeler 6 is guided in the bearing bushing 13, which via a pin 12 is permanently connected to the leveling feeler 7. It is possible for the pin 12 to slide in a slot 19 within the switch feeler 6.
  • a compression spring 9 mounted which is inserted so as to be under a preload.
  • FIG. 4 shows a further possible configuration of the switching means in accordance with FIG. 3.
  • the switch element 20 of the switch 14 has a follower roller 21 at its end, which contacts a slanted surface 22 on the upper end of the switch feeler 6.
  • the roller 21 may penetrate through a slot-like opening provided in the upper part 25 of the leveling feeler 7 in order to contact the slanted surface 22.
  • the upper part 25 of the leveling feeler 7 is permanently connected with the switch 14 by means of an angle piece 24.
  • the switch feeler 6 with the follower roller 11 may move into the recess or switch activating groove 5 and thus produce a signal.
  • FIG. 5 shows the contact point in a cross-sectional side view. It can be seen that the sliding shoe 10 is still riding on the outer wall surface of the strut 1, while the follower roller 11 associated with the switch feeler 6 is positioned in the recess 5. Therefore only the difference in depth due to the recess 5 is relevant for the generation of a switching signal; any inaccuracies or tolerances (play) between the hollow beam 3 and the struts 1, 2 are of no account.
